You can be dismissive all you want, but the point is to acknowledge you don’t understand everyone’s situation and you can’t make sweeping generalizations like “I did it and I can judge you if you _didn’t_ do it”.
Goes both way, yes.
History has examples of extremely underprivileged people not compromising on the values even when facing death or torture.
You can also acknowledge that most people abandon their principles long before they are anywhere close to starving and will not be harmed (physically) by being reminded of that.
